Sometimes when a 787 has to be moved from Runway 11-29 several airplanes have to be moved out of the way, usually they are parked on the taxiway. There was a lot of traffic today so the 787 was probably parked at the fuel dock and then moved back to 11-29.

Matt, I notice the codes next to the registrations (ZA117, WE194, YH614, etc.) Are those flight numbers? Do they stay with individual aircraft before delivery or do they change for every flight i.e. first flight, customer flight? How are they announced? Zulu Alfa 117 or Boeing 117?
